Abstract

L'amortisseur hydraulique comporte un piston 2 monté dans un cylindre 1, et solidaire d'une tige 3 guidée par une pièce d'extrémité 4. Un dispositif d'étranglement 11, 12, associé à chaque partie 6, 13, du cylindre, en regard de chaque face 9, 14, du piston, peut se fermer sous l'action du liquide refoulé par un mouvement brusque du piston 2. Un soufflet de compensation 8 communique avec l'atmosphère. La tige 3 du piston est entourée par un soufflet d'étanchéité 5, fixé à la face 9 du piston attenante à la tige 3, et à la pièce de guidage 4, montée à l'extrémité de la partie correspondante 6 du cylindre. Application aux amortisseurs hydrauliques de conduites, notamment pour des centrales nucléaires, pour en améliorer l'endurance et la sécurité, en supprimant les fuites de liquide autour de la tige du piston
